Susan had been attempting a letter to her grandfather when the giggling started. At first she'd stopped, waited to see if the giggling would continue, and when it didn't she simply resumed her writing.
Then it started again. "All right, come on out," she said, though she wasn't sure what exactly she was talking to.
The only response was another giggle.
"You're doing yourself no favors," said Susan. "Come out, or I'm going to be cross with you, and you don't want that."
Whatever Susan had expected, the creepy doll that came out from under her bed was not it. She would also probably have a lot of difficulty sleeping in that bed tonight. Or ever. It began walking towards her with a butcher knife in hand, and while Susan could easily get to the poker from where she was... really?
"Stop right there," she told it. "Unless you're getting ready to go to the kitchen and make dinner, there will be none of that."
The creepy little thing didn't stop, advancing on her about as quickly as you'd expect from a doll that you were actually watching.
Susan folded her arms and frowned at it. "What did I just say?" she asked in a pointed tone. "I've told you once to stop. If you don't, you're going to be punished. I am entirely serious about this."
To her surprise, the doll stopped, looking confused even though its face couldn't actually move.
"That's right. Now put the knife down and we'll both behave like civilized people, all right?"
Of course it wasn't that easy, but with some more of the same, Susan was able to get it to listen and cooperate, which was why anyone who passed by the open door to 512 would see Susan sitting in her desk chair, reading a textbook aloud to a calm-seeming killer doll that was sitting on her bed.
She might burn that bed later.
